Figure 2 is avertical section of iig. 1, through the line a; x, t i Similar lettersof reference indicate corresponding 'lhsdoor is cast in a single piece, by so setting sand I cores in the mouldfthat the iron partitions 'marked A will be left, the core-sand being afterward removed through apertures'in the top of the door, which are' It will be seen that by this arrangement of the partitons A, a serpentine or zigzag -channel is made through the door.

The water is introduced through the pipe screwed into the projecting limb C of the door; it passes uuder the rst partition, and over the second, and so on' through the door, as indicated by the-arrows, and `is discharged through the aperture D in the projec-1 tion E.

By this means the door may be kept cool, while by the rapidvcircnlation produced, the water will not `be so heated, after itis discharged, as to be unfit for `eooling the tools of `the workmen. v
